What is a Thriller?

As my project is based around the genre of thriller, it seems logical to define it.
The term thriller is rather broad, and can feature in literature, film and television. Moreover, the thriller genre generally overlaps other genres, creating sub-genres. This is one of the appeals on thrillers - no two are the same, due to the endless possibilities with plots and storylines.
The common denominators in thrillers include the fast-paced action, and the resourceful heroes, who strive towards thwarting the uber powerful, superbly equipped villain.
Extensive use of suspense, red-herrings and cliffhangers add to the attraction of the genre. The plot usually contains a villain, who musters up obstacles which the hero must overcome. The flexible genre engages the audience through a dramatic rendering of psychological, social and political tensions.
The great thriller director Alfred Hitchcock once said that thrillers allow the audience "to put their toe in the cold water of fear to see what it is like."

Welcome To My Blog.

Hello, and welcome to my blog. As part of my Media Studies coursework, we have to create a blog, and regularly update it with information regarding our project. The project is to create a short trailer for a movie. The genre for the movie is thriller.
Over the next few weeks and months, I hope to document various media, and brainstorm many ideas that will help me create an amazing piece of work.
